The Challenge

Replicability

Potential for the widest possible replicability and relevant learnings for future CSP project applications.

Plant Capacity

Logical minimum capacity for a CSP plant to minimize requirement for Government support whilst

maintaining relevance for future development.

Dispatchability

The Project should include a thermal energy storage (TES) system which will allow the CSP plant to

generate electricity when needed, and to provide the benefits of firm capacity to the local transmission

network.

Pathway to Cost Reduction

Select state-of-the-art technology which offers the highest potential for cost reduction of the three

compared technologies: parabolic trough, linear fresnel and tower.

The Technology

Molten salt tower overview

Provides dispatchable renewable energy.

Offers unique flexibility since the energy collection and energy delivery processes are decoupled.

Energy is collected when the sun is shining, but only converted into electricity when it is demanded.

No round-trip losses associated with storing the energy for later use.

Higher temperature increases efficiency and reduces storage costs.

Rationale for Site Selection

Ideal site for the proposed plant, including world class direct solar irradiation;

Fringe of grid connection will provide significant network benefits;

Proposed off-take arrangements include a combination of electricity retailers and a large iron ore mining operation;

WA Government and local community are supportive of such activity;

Strong demand for peak and especially shoulder generation;

Excellent prospects for further roll-out of solar thermal power generation with storage in end of grid and off-grid applications, with an emphasis on powering the mining sector.

What did the feasibility study test?

Solar radiation resource

CSIRO heliostat design compared with Abengoa

Optimum storage capacity

Socio-economic, environmental and network benefits

Cost to install a CSP plant in a remote area of Australia

Pathway to cost reduction

Feasibility of implementing the project

22


-Confidential-

What were our findings?

World class DNI

Abengoa heliostat design has commercial maturity, CSIRO design has optical benefits

Storage capacity increased from 3 to 6 and finally 7 full load hours

Lack of awareness by grid operator of characteristics / benefits of CSP with storage

Cost to install a CSP plant in a remote area of Australia

Pathway to cost reduction – project learnings, pipeline, supply chain, and increased capacity lead to competitive LCOE

Potential to be a feasible project

23


-Confidential-

What are our recommendations to reduce costs?

Create a baseline - build the first project

Encourage market demand (through combination of RET, and ARENA/Government programmes)

Facilitate a pipeline of projects to create a local supply chain; local technical, project and financial expertise; leading to lower costs

Increase plant scale from 20MW to 100MW+

Focus on value creation as well as reduced cost
